When addressing the needs of problematic skin, active ingredients such as retinol, benzoyl peroxide and alpha-hydroxy acid are often found in recommended skin care products. Their effectiveness varies; however dermatologists agree that mixing these strong ingredients can be counter- productive.
Retinol and benzoyl peroxide are exfoliating agents that clear existing acne and prevent new blemishes from forming due to its drying effects. When mixed together, or even layered, the skin can experience excessive peeling, flaking, redness, and blistering, scarring and unwanted pigmentation.
Alpha-hydroxy acid- a chemical found in natural products acts as an exfoliating agent and can be used in combination with retinol. When using these together, the AHA should be applied in the morning whereas retinol is to be applied at night.
These aforementioned ingredients may cause increased sun sensitivity. Therefore, it is critical to wear a good, daily sunscreen to counteract UV sensitivity.
If you use retinol, benzoyl peroxide and/or alpha-hydroxy acid, be mindful of the amount you use. These ingredients are potent and often cause irritation. When using products with these ingredients, dermatologists suggest using small amounts at first in order to build tolerance.
